Every time I do a fresh install, Google Chrome asks me for my passphrase. I have searched high and low in Google's help forum and have yet to receive or find any form of response.
When I do a fresh install, if I try to enter the passphrase (with all possible passwords I can recall) nothing works and I can't recover my extensions, bookmarks etc.
On the other hand, if I wait a bit, everything falls into place.
I close that window asking for passphrase and all my extensions, bookmarks are back.
The failure to enter a proper passphrase code gets me a message to change my passphrase in my account settings. Who knows where that is! No one at Google's forum seems to know anything about this passphrase.
